Model Answer

India’s renewed thrust on nuclear energy represents a strategic pivot toward clean, reliable, and secure energy, essential for sustaining high economic growth while meeting climate commitments like net-zero by 2070. With nuclear power contributing only ~3% of electricity today, scaling it to 100 GW by 2047 reflects both necessity and ambition.

Recent Reforms in India’s Nuclear Sector

1. Legislative Overhaul – SHANTI Act, 2025

The SHANTI Act, 2025 marks a paradigm shift by replacing earlier laws and creating a unified legal framework. It:

a. Enables private and foreign participation, ending state monopoly b. Rationalizes civil liability, aligning with global conventions c. Grants statutory status to AERB, strengthening regulatory oversight

This reform addresses long-standing bottlenecks that had stalled global collaborations.

2. Opening the Sector to Private Capital

For the first time, private entities can build, own, and operate nuclear plants under licensing conditions. This is crucial to overcome the capital constraints of a purely state-led model.

3. Promotion of Advanced Technologies

Policy support for Small Modular Reactors (SMRs) and indigenous designs signals a shift toward: a. Lower capital cost reactors b. Flexible deployment for industrial use c. Integration with emerging sectors like hydrogen

4. Strengthening Regulatory and Institutional Framework

a. Statutory backing to the regulator enhances transparency and safety b. Creation of dispute resolution mechanisms improves investor confidence

5. Progress in Indigenous Nuclear Programme

Milestones like the Prototype Fast Breeder Reactor (PFBR) signal advancement in the three-stage programme, critical for long-term thorium utilization and energy independence.

Challenges in Achieving Long-Term Targets

1. High Capital Intensity and Financing Risks

Nuclear energy involves massive upfront costs and long gestation periods, making it less attractive compared to renewables. Even with reforms, mobilizing large-scale private investment remains uncertain.

2. Land Acquisition and Public Resistance

Projects often face local protests and environmental concerns, delaying timelines and increasing costs, as seen in multiple nuclear sites.

3. Regulatory and Liability Concerns

While liability reforms attract investors, critics argue that capping liability may dilute accountability, raising safety concerns.

4. Technological Constraints

India’s thorium-based Stage III remains underdeveloped

Transition from experimental reactors to commercial deployment is slow

5. Supply Chain and Geopolitical Risks

Dependence on a few countries for fuel and technology exposes India to external vulnerabilities, especially during geopolitical disruptions.

6. Human Resource Deficit

Expansion to 100 GW requires a highly skilled workforce, which current training capacity may not adequately support.

7. Water and Environmental Constraints

Nuclear plants require significant water for cooling, creating challenges in water-stressed inland regions.

Conclusion

India’s nuclear expansion is undeniably both an economic necessity (baseload energy for growth) and an environmental imperative (low-carbon transition). The SHANTI Act and associated reforms provide a strong institutional foundation; however, financial viability, regulatory clarity, technological maturity, and public acceptance will determine success. A calibrated strategy combining indigenous innovation, global partnerships, and sustainable financing is essential to transform legislative ambition into operational capacity.
